So what is the difference between what I do and what other sellers are doing?
First step is I take your domain and set it up with mostly Google properties. These are 301 redirects that Google uses to rank its own stuff. Essentially what you are getting is a DoFollow link from Google, Google Images, Google Maps, Google Plus, Google Custom Search, Google Public DNS, EDU, and others.
Once this step is done the redirects are then embedded on up to 200 indexed sites. I say up to 200 as it really depends on indexing and what Ahrefs can pick up. But needless to say what I do is very solid.
Now let me explain this. This is not the same 200 sites for each redirect. I am using 1000's of indexed sites that have a range of DR as low as 20 and above 70. They are randomly selected. This not only makes the DR stick but also increases the UR.
